This is along the same lines as "The Grey Apparatus" or the "Green Foreman" And the presets are useful and there is much to tweak , my 4 gb laptop handles it easily, so it seems easy enough on the processor, it is a go to synth for initializing soundscapes or ambient layers. nano version is a nice thoughtful inclusion, love this one.

one of the best free synth's I've found.. has really nice presets and also has a mini (nano) version included in the download in-case its too big for your screen.. i definatly recommend downloading this!! you wont regret it.. :)
